Most UFO's are things that are misconcepted by unknowing spectators. they mistake flights of birds, planes,... for spacecraft. 99,99% can be proven by checking date, time,... by a professional institution. Don't forget the confessions of hoaxes either.

Science can prove pretty much nowadays but I still think there will be a certain border we'll reach one day.
Perhaps we'll find the Origin of Universe etc. But I doubt we'll ever traval at the speed of light or create a costum- made human or even Stretch the length of human life (150+ years average)

Stephen Hawking has pretty much summed up where the Universe came from and used evidence to support his claims. He's also had theories on time-travel and the like... I suggest someone find his vids on youtube, they're mesmerizing.

I dunno if Science has ALL the answers, but it sure as Hell has more than anything else floating around out there. Scientific discoveries have exponentially helped advance the human race in the last 50 years, and at this going rate, we'll have probly made groundbreaking achievements in DNA alteration and space exploration within the next 10 years.
